. .GVRIPPING DEVICE.

SPECIFICATION forming part of Letters Patent Ila-736,173, dated. August 11, 1903.

Application filed March 11. 1903.

To aZZ whom it may concern.-

Be it known thatI, BERT WILLIARD TRUs- COTT, a citizen of the UnitedLStates, and a resident of Cleveland, county of Cuyahoga,

State of Ohio, have invented certain new and useful Improvements in Gripping Devices, of which I hereby declare thefollowing to be a full, clear, and exact description, such as will enable others skilled in the art to which'it appertains to make and use the same.

My invention relates to improvements in gripping devices for. the collapsible coiling of a veneer-barrel machine; and the object of the device is to provide mechanism for grasping the edge of' the piece of veneer simultaneously with the act of tightening the collapsible portion of the drum, adapted also to release the edge of the piece of veneer and simultaneously collapse the drum, so that the completed barrel can be removed.

My invention consists in the cam-shaped locking-dogs and intervening spring mechanism, as hereinafter described, shown in the accompanying drawings, and specifically 5 pointed out-in the claims.

In the accompanying drawings, Figure 1 is a perspective View of the machine in which the coiling-drum is employed." Fig. 2 is an end View of the collapsible drum. Fig. 3 is a similar view showing the parts of the drum relaxed and the gripping parts separated for the admission of the veneer.

In the views, 1 is the drum, mounted upon 8 to the mainportion.

9 is a rod passing through the heads 10 of the .drnm and provided with a handle portion 11, by means of' which it can be rotated.

Serial No. 147,275. (No model.)

the drum, as seen in Fig. 2. The other dogs 13 engage springs 15, which are secured at their inner ends to the inner surface of the drum and are attached at their outer ends to the longitulock it rigidly, while the dogs 13 will raise the springs 15 and with them the bar 16 and pinch the veneer between the-bar. and the edge F of the drum. The hoops fed through the guides 5, therefore, are then fed to the drum and their ends nailed in place. The

roller 6 is then brought down upon the drum and the hoops and veneer thereunder are compressed by the roller as the drum revolves.

A single piece of veneer can be coiled by means of this device, or narrow pieces can be fed underneath the hoops one at a time to form alternating layers until the complete barrel is formed and the hoops nailed into place. In this manner a barrel can be much more cheaply constructed than by employing large single pieces of veneer, since smaller pieces and remnants can be used.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a drum ofa veneerbarrel machine mounted'upon a rotating shaft and provided with a hinged portion separated from the drum on one edge by an open slot, of a rod inserted in the drum-supports, camshaped dogs on said rod adapted to engage and force back the collapsible portion, a gripping device for veneer in the edge of the drum adjacent to the-open slot, substantially as described. ,7

2. In combination with the collapsible drum of a veneer-barrel machine, a device .for forcing back and locking the collapsible portion of the drum, a device for simultaneously compressing the edge of a piece of veneer against the inner face of the edge of the longitudinally-placed bar underneath the free edge of the drum, springs connecting said bar and drum, a longitudinal rod in said 15 drum, cam-dogs on said rod engagng said springs and a handle for said rod, substantially as described.

In testimony whereof I hereunto set my hand this 28th day of February, 1903.
